If you are truly proficient in C++ then you probably are better
off with C++ at this point than using languages like D, Rust or
Swift, at least for long term commercial projects.
* Do D compilers generate more efficient code compared to C++
compilers?
No. The best D compilers use backends written for C/C++
(llvm/gcc).
* Can D generics do everything C++ templates can (are they
Turing complete for instance) - and what additional
capabilities does D have that would make a significant
difference to the way templates are used in C++?
Certain things are more tedious in C++, like adding methods based
on template parameters. Compile time reflection is also more
tedious in C++.
Yet again, certain other things look syntactically better in C++
and other things look better syntactically in D.
* How does D's performance compare with Java when it comes to
concurrent applications or garbage collection?
Java has much better garbage collectors. Concurrency frameworks
have been more thoroughly tested in Java and C++.
* How stable is D? Can one use it without fear that the next
version will significantly change the language and therefore
one would have to rewrite?
Java and C++ are more mature and have been more stable.
